CVE-2017-5262
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn versions 4.3.2-R4 and prior of Cambium Networks cnPilot firmware, the SNMP read-only (RO) community string has access to sensitive information by OID reference.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIn Cambium Networks cnPilot firmware versions 4.3.2-R4 and prior, the SNMP read-only community string allows access to sensitive information through specific OID (Object Identifier) references. This represents an information disclosure vulnerability where the typically low-privilege RO community string exposes more sensitive data than it should.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify device model and firmware versionAccess the cnPilot web interface or use SNMP to query the device sysDescr OID (1.3.6.1.2.1.1.1.0) or check via CLI with 'show version'. Identify the exact model (R190v, E410, R190n, E400, or E600) and firmware version.Affected if The device is a Cambium cnPilot model R190v, E410, R190n, E400, or E600 running firmware version 4.3.2-R4 or earlier.
-
Verify SNMP service is enabledCheck via cnPilot web interface under Services > SNMP, or query with snmpwalk against the device using the SNMP community string to confirm the SNMP service responds.Affected if SNMP is enabled and responding to queries.
-
Check SNMP community string configurationIn the cnPilot web interface under Services > SNMP, examine the Read-Only (RO) community string field. Note whether it retains the default value (typically 'public') or has been changed to a custom value.Affected if The SNMP RO community string is set to a default or weak value (e.g., 'public') and allows access to sensitive OIDs.
-
Test for sensitive OID access via RO communityUsing snmpwalk with the RO community string, query sensitive OIDs such as the running configuration OID or wireless client information OIDs. Compare the data accessible to what should be restricted from RO access.Affected if The RO community string provides access to OIDs that should require write access or higher privileges, exposing sensitive system configuration or client data.
You are affected if you run any of the listed cnPilot models (R190v, E410, R190n, E400, E600) on firmware version 4.3.2-R4 or earlier, have SNMP enabled, and are using the default or weak RO community string that exposes sensitive OID data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate cnPilot firmware to a version beyond 4.3.2-R4, change the default SNMP community strings to non-default values, and implement network access controls to restrict SNMP access to authorized management stations.
